The process of
sending back
the light rays
which falls on
the surface of
an object –
Reflection
The object having
polished , shining
surface reflects
more light than
object having
unpolished, dull
surface
Silver metal is good
reflector of light
Laws of reflection of light
The incident ray , the normal to
the mirror at the point of
incidence and the reflected ray , all
lie in the same plane.
The angle of incidence is equal to
the angle of reflection.
It is a mirror which has the shape of a piece
cut out of a spherical surface
Concave mirror
It is a spherical mirror , whose reflecting surface is curved
inward or faces towards the centre of the sphere.
CONVEX MIRROR
It is a spherical mirror whose reflecting surface is curved outward
 Pole (p) – centre point of the reflecting surface of a spherical
mirror. It lies on the surface of the mirror.
 Centre of curvature (C)- Centre point of the sphere , in which
the reflecting surface of a spherical mirror forms a part of this
sphere
 Radius of curvature (R)- the radius of the sphere of which the
reflecting surface of a spherical mirror forms a part.
 Principal axis – Is a straight line passing through the pole and the
centre of curvature of a spherical mirror.
 Aperture- the diameter of the reflecting surface of spherical
mirror
Focal length – the distance between the pole and the principal focus
of a spherical mirror
A number of ray parallel to the principal axis are falling on a
concave mirror and the reflected rays are all intersecting at a
point on the principal axis of the mirror. This point is called the
Principal focus of the concave mirror
Principal focus of the convex mirror – the reflected rays appear to come from
a point on the principal axis
 Rays of light coming from infinity,
making different angles with the
principal axis get focused at different
points.
 The plane formed by these points
is perpendicular to the principal axis
and passes through the principal
focus.
 This plane is the principal axis
For a spherical mirror of small aperture,
 The principal focus F lies midway - between the pole P
and the centre of curvature C
 The radius of curvature is found to be equal to twice the
focal length

 Commonly used in torches, search lights
 Vehicle headlights to get powerful parallel beams of light
 Often used as shaving mirror to see large image of the face
 Dentists use concave mirror to see large images of the teeth
of patients
 large concave mirrors are used to concentrate sunlight to
produce heat in solar furnace

Diminished Virtual and erect
Commonly used as rear-view mirror in vehicles, because
 Enabling the driver to see traffic behind him to facilitate safe
driving
 They always give an erect, though diminished image
 View as they are curved outward
 Enable the driver to view much larger area than would be
possible with a plane mirror
Real image Virtual image
Inverted Virtual
Can be formed on the screen Cannot be formed on a screen
The distance towards the
image and its height can be
measured directly
The distance towards the image
and its height cannot be measured
directly
 It is expressed as the ratio of the height of the image to the
height of the object
 It is usually represented by the letter
 Magnification produced by a spherical mirror gives the relative
extent to which the image of an object is magnified with respect
to the object size
m = Height of the image / Height of the object
Magnification m is also related to the object distance (u ) and
image distance (v)
 Object is taken to be positive as the object is usually placed
above the principal axis
 Height of the image should be taken as positive for virtual
images, however taken as negative for real images
 A negative sign in the value of the magnification indicates
that the image is real
 A positive sign in the value of the magnification indicates that
the image is virtual
